Firefighters in about five trucks responded to an alarm that was tripped around 7 p.m. Friday at the Plaza Terrace apartments on 30th Street NW, but it was an apparent false alarm.

Battalion Chief Akbar Bennett said that in addition to the alarm a resident noticed the smell of smoke in the elevator shaft.

He said firefighters smelled the odor, which may have been electrical in nature. However, they could not find the source if the odor and saw no smoke or flames. They searched the maintenance room elevator shaft and roof and found nothing.

Bennett said tenants were told to stay temporarily in their apartments until firefighters could figure out what was going on. No one was hurt.
